Note: Models 1.1 and 1.2 use an early feeding composite score, Models 2.1–5.2 use individual early feeding variables to consider differential relationships between early feeding challenges and feeding challenge classification scores. All models run without control variables and then controlling for child age and autism traits using SRS-T Score.
